TYPE-WRITING MACHINE.

To all whom it may concern:

Be it known that I, ALFRED G. F. KUROW- em, a citizen of the United States, residing in Brooklyn, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Type 'riting Machines, of which the following is a specification.

This invention relates to tally-strip mechanism, such as used in typewriting machines, etc.

One object of my invention is to makeit feasible and convenient to make carbon impressions upon the tally-strip of entries made upon a bill or other primary worksheet, in any selected column in said bill.

I provide at the right-hand end of the platen a special tally-strip platen, which may be made of substantially greater length than the ordinary tally-strip platen, and is illustrated as being about three times as long. The tally-strips are of the usual width, but provision is made whereby they may be adjusted to different places along this special platen, to receive carbon impressions of numbers written in 'difi'erent columns on the primary work-sheets, as may be desired from time to time.

The tally-strip is carried upon spools, comprising a supply spool and a Winding spool, the tally-strip extending from the supply spool around the tally-strip platen to the winding spool, and by means of a pawl-and-ratchet mechanism connected to the winding spool, the strip can be line-fed regardless of the position to which the spools and strip may be adjusted along said special platen; this line-feeding operation preferably occurring automatically at the operation of releasing the usual feed-rolls from the bottom of the main typewriter platen. Provision is also made whereby the usual carbon strip, which may also be supplied from aspool, may be re-wound on its spool by means of a finger piece, regardless of the position to, which the spools are adjusted along the special platen.

The three spools and strips are shift'able as a unit to the different desired positions along the tally-strip platen, and they may be held in any of three positions along said platen by means of a releasable lock.

The tally-strip mechanism may be supported on an auxiliary frame carried on the platen frame. The auxiliary frame may Specificationpf Letters Patent.

spools are all shifted as a unit to adjust the strips. The shifting frame may be locked in adjusted position,ras by means ofa latch,

which engages notches at intervals along one of said spindles. The spindle carrying the carbon roll spool may be rotatable, as by means of a crank, to re-wind the carbonstrip, the spool having a splined connection with the spindle to permit adjustment.

In the accompanying drawings, Figure l is a front elevation of my improved tallystrip device, attached to the platen frame of an Underwood typewriter. Fig. 2 is a right end view of Fig. 1, showing the method of line feeding the tally-strip and a work-sheet in position. Fig. 3 is a perspective of the frame carrying and confining the carbon roll, tally-strip and winding spool, showing also the method of locking the said frame in position against accidental displacement. Figs. 4, 5 and 6 are details of the locking device.

The usual platen 1 has an axle 2 jou'rnaled in .the ends 3 of a platen frame 4. Between the platen 1 and a platen frame end 3 is a segmental platen 5 Front and rear pressure rolls 6, 7 run along the under side of the platen 1 and are mounted on shafts 8 carried by arms 9 pivoted on a rod 10 fixed between the platen frame ends 3. These pressure rolls 6, 7 are castofi the platen 1, by depressing a lever 11 pivoted at 12 to a platen frame end 3, as shown in Fig. 2, and connected with a link 13 to a crank arm 14: on a shaft 15 having flats or'cams 16 to engage'and rock the arms -17 formed integral with thearms 9, causing the latter to swing outward from the platen 1 on rod 10, in the well-known manner. v

Over the segmental platen 5 is a Winding spool 18 for a tally-strip 19 and a carbon roll and strip 20. v This winding spool 18-is splined with a screw 21 to a hollow shaft 22 supported on a rod 23 fixed between the platen frame ends 3, and is rotated or moved a step, each time the pressure rolls 6, 7, are cast off the platen 1 to remove or insert a work sheet 24. This is accomplished by a link 13 between the release lever 11 and cam shaft 15, normally engaging a tooth of ratchet wheel 26. The latter is fixed to hollow shaft 22, so that when said lever 11 is depressed, the link 13 and dog 25 rise, moving the ratchet wheel 26 on shaft 22, and turning spool 18 a step. Upon restoring the pressure rolls (5, 7 to the platen 1 again, dog 25 drops and takes up a position under the next tooth. v

The tally-strip 19 and carbon roll 20 are mounted to rotate upon sleeves 27 fixed to a shifting frame 28, which is supported mainly upon a rod 29, fixed in an arm 30 pivotally supported upon the shaft 22, which acts with the shaft 31 as a guide for the said frame 28. This frame 28 forms the right-hand retainer for the tally-strip 19, the carbon roll 20 and winding spool 18. The latter also has a left confining plate 32 formed of the frame as shown in Fig. 3. If the frame 28 is moved laterally along the rod 29, the carbon roll 20, strip 19 and the winding spool will be carried along therewith. as a unit. a 4

To prevent the carbon roll 20 and strip 19 from sliding off the sleeves 27, the left confining plates 32 are locked to the ends of said sleeves by means of sliding latches 33 shown in Fig. 1.

In order that the frame 28 may not become displaced during the operation of the machine, there is provided on said frame 28 a latch ,34 kept constantly seated by a spring 35 in one of a series of notches 36 in the rod 29. To shift the frame 28 into a new position, it is simply required to depress the finger piece 37 of the latch 34, which will then clear the notch 36 and be free to move laterally along the rod 29. i

The carbon roll 20 may be rewound by turning a crank 38 fixed on the end of a hollow shaft 31, to which the carbon roll spool 40 is splined with a pin 41 in the hub 42 of the left confining plate 32 The said hollow shaft 31 is supported on the rod 43 fixed to the pivoted arm 30, 'hereinbefore mentioned.

The rods 29 and 43 fixed in the arm 30, are supported at their left ends in the open bearings 44 of an arm 45, similar to the arm 30, said arms 30 and 45 comprising with said rods an auxiliary frame on which the frame 28 and spools are mounted. On this arm 45 there is a sliding bar 46 capable of being notch 36, and the frame 28, carrying the carbon roll 20, tally-strip 19 and winding spool 18, may be moved along the rod 29 into position, and again locked by said latch 34.

As the work sheet 24 overlaps the carbon I 20 and tally strip 19, the type impressions made upon the work sheet are duplicated by the carbon upon the tally strip. \Vhen the feed rolls 6, T are released to remove the work sheet 24 at the completion of the writing, the dog 25 on the release-lever connecting-link l3 automatically line-feeds the tally-strip and carbon. If another class of bills is then to be written, in which it is desired that the column of items which are to go upon the tally-strip shall be in a different columnar position on the bills, the spools may be adjusted as a unit along the platen to bring the strip to position to receive the carbon duplicates of such items.

It will be noted that the tally-strip unit may be locked in three different positions, thus giving a wide range of usefulness to the machine; although there may be even more locking positions for the device if desired. Thus it will be seen that the narrow tally-strip can be adjusted to take in any selected column from a number of columns on the primary Work-sheet.

This device, it will be seen, makes it unnecessary to provide a triple-width tallystrip, and also overcomes the objection to such a wide tally-strip that the items in the three columns on the primary work-sheet would all be reproduced on the wide tallystrip, even though the items on only one column were wanted on such tally-strip. Moreover, the objection is avoided of the undue weight of a triple-width tally-strip, which would be liable to reduce the speed of operation of the typewriter carriage.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others. Having thus described my invention, I claim:
